LOW-PRESSURE GAS BURNER.

Application filed February 28, 1922. Serial. No. 540,041;

To all whom it may concern:

Be it known that J osnrn P. SHAW, JOSIAH WILL SPURGIN, and SIMEON D.LYNN, citizens of the United States of America, residing at Okniulgee,in the county of Okmulgee and State of Oklahoma, have invented new anduseful Improvements in Low-Pressure Gas Burners, of which the followingis a specification.

The object of the invention is to provide a gas burner suitable for useunder conditions in which-the pressure is low whereby a saving oreconomy in the consumption of the fuel may be secured through a meansinvolving the presentation thereof at the combustion point with a properadmixture of air to insure complete combustion; and with this generalobject in view, supplemented by others which will appear in the courseof the following description the invention consists in a construction,combination and relation of parts of which a preferred embodiment isshown in the accompanying drawing, wherein:

Figure 1 is a plan view partly in section of a burner embodying theinvention.

Figure 2 is a transverse sectional View of the same on the planeindicated by the line 22 of Figure 1.

Figures 3 and 4 are opposite end views of the casing.

The burner consists essentially of a feed pipe 10 adapted for connectionwith the gas line and extended axially through a casing 11 ofcylindrical form open at one end as shown at 12 to provide for anunobstructed air inlet spanned by a spider 18 serving to preserve aproper relation of the feed tube and casing and closed at the oppositeend by a head 14 having a central opening for the reception of theadjacent end of the feed tube which in turn is closed by a removable cap15.

The casing is provided with socket sleeves 16 for the reception of theburner tubes 17 and are obstructed at their inner ends to prevent theinward displacement of the burner tubes by-seats or flanges 18 formed bythe inward extension of the wall of the casing, and radiating from thefeed tube in axial alignment with the sockets 16 are nipples 19 arrangedat their outer ends in the planes of the inner ends of the sockets andfitted with caps 20 in which are formed small orifices. for the escapeof the gas in jets designed to axially traverse the burner tubes andinduce a current of air therethrough from the casing so as to produce aneffective mixture of the gas and air before reaching the outlet ends ofthe burner tubes and thereby insure a complete combustion at saidoutlets.

Obviously the burner tubes may readily be replaced when burned out orotherwise rendered inoperative or ineffective and likewise the otherparts of the burner may be readily disconnected for cleaning or repair,the feed tube and easing being made of any desired length to suit thedimensions of the furnace in connection with which the same may be usedand any desired number of burner sockets being applicable to the same apractical spacement thereof being longitudinally at a distance of fourand nine sixteenths inches from center to center but obviouslybeing'variable in this respect to suit local conditions and especialrequirements in service.

The feed tube which constitutes a gas chamber of relatively largediameter and hence capacity as compared with the nipples which conveythe gas from said feed tube into the burner tubes so as to prevent backfiring or combustion in the casing, may and preferably is of a diameterfor example of two inches whereas the nipples may consist of one quarterinch tubing and with the orifices for the outlet of the gas consistingof a hole of three thirty seconds inches in diameter drilled in thecenter of the cap with which the nipple is fitted at its outer end.

Having described the invention, what is claimed as new and useful isz 1. A low pressure gas burner "havin a tubular casing provided withradially aisposed open ended sockets and a tube disposed axially in thecasing and provided with radially disposed nipples arranged respectivelyin axial alignment with said sockets and having reduced outlet orificesat their outer extremities, the casing being open and closedrespectively at its opposite ends, and burner tubes removably fit+ tedrespectively in said sockets.

2. A low pressure gas burner having a tubular casing provided withradially disgas feed 7 Q i j 1349x954 V posed open ended sockets and agas feed fitted in the sockets in contact With said tube disposedaxially in the casin and proseats or flanges. 10 vided with radiallydisposed nipples ar- In testimony whereof they afiix their sigrangedrespectively in axial alignment With natures.
